Abstract

The galvanic corrosion behavior of titanium/ Cu-Ni Alloy / high strength steel in multiphase material system has been studied under open circuit conditions using a zero-resistance ammeter (ZRA) in seawater. After the tests, the surface morphologies of the samples were detected by SEM. These results have been compared with results estimated from the polarization curves according to the mixed potential theory (imposed potential measurements). Results showed that Galvanic corrosion behavior of titanium (TA2)/Cu-Ni Alloy (B10) / high strength steel (921A) fulfill the mixed potential theory, 921A acts as the anode and bothTA2and B10 act as the cathodes. The overall galvanic reaction is mainly governed by the anodic oxidation of the 921A.
